Gusty southwest winds persist across the Dispatch Area through
2000L. Expect overnight winds to be light and diurnally driven.
Relative humidity values remain well above critical values, with
good to excellent overnight humidity recovery. There is a low, 10 to
20 percent chance of light rain or virga across the mountains
through early Sunday. Similar temperatures, 1 to 6 percent higher
humidity, and gusty southwest winds on Sunday with increasing shower
and thunderstorm chances.

...Cody dispatch area (includes fire weather zones 275...276...
282...283...285...286...287...288...and 289)...

Gusty westerly winds persist across a majority of the Dispatch Area
through 2000L, with gusts possible for high elevations through
2300L. Zone 275 and 282 can expect relatively light winds through
1900L before winds shift to be from the northwest and breezy until
sunrise Sunday. Although relative humidity values remain above
critical values, elevated fire weather conditions are expected
through 1900L. There is a low, 20 percent chance of light rain or
virga for Zone 289 between 1700L and 0700L Sunday and for northern

values remain above critical values, elevated fire weather
conditions are expected through 1900L. There is a low, 20 percent
chance of light rain or virga for Zones 279, 280, and 289 between
